title: [Effect of treatment with p-fluorophenylalanine on the mating capacity of industrial polyploid yeasts].
abstract: Brewing yeast strains of the genus Saccharomyces uvarum (carlsbergensis) were grown on media containing p-fluorophenylalanine (p-FPA). After the treatment, non-sporulation colonies were selected, and these were mated with haploid strains of flocculent and amylolytic yeasts of the genus Saccharomyces. The selected hybrids, which carried the greater part of the parental genetic markers and produced asci containing 2,3 and 4 spores per ascus, were placed on sporulation medium. Some aspects of the probable action of p-FPA are discussed.
